This lesson offers teachers the opportunity to listen to ways in which students describe and calculate volume. After the Warm-up, three activities are given, but it is not expected that students do all three. As the activities progress, there is one additional element missing from the Which Three Go Together? activity. The choice of which activities to use is left to the teacher, based on how much scaffolding the students may need. This lesson can take 1–2 days if students facilitate their creations with other groups.
